I didn't like it in my QX30 that I previously had. It was rough and didn't save much on mpgs. Right now I'm not using on my Bronco Sport, to get a baseline idea of what the gas mileage is without it. Once I feel like I have a good gauge on that, I'll probably turn it on. The bronco sport system is a lot smoother than what I had expected so wouldn't mind using it as much
